RUBBER HEEL ATTACHMENT FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 638,228, dated December 5, 1899.

Application filed Au ua 7, 1899.

To all whom, it may concern:

Be it known that I, CARA S. FERGUSON, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Rubber Heel Attachments for Boot-s or Shoes, of which the following is a specification.

My invention relates to the improvementof rubber heels for shoes and boots; and the objects of my invention are to provide an im proved heel of this class adapted to be attached to an ordinary boot or shoe heel, to so construct the same as to insure the retention of a close and desirable contact of the rubber with the surface of the leather heel, and to produce other improvements the details of construction and arrangement of which will be more fully pointed out hereinafter. These objects I accomplish in the m ariner illustrated in the accompanying drawings, in which Figure 1 is a detail View in perspective of a shoe-heel having my improved attachment connected therewith. Fig. 2 is a detail view in perspective of the rubber heel attachment. Fig. 3 is a similar view in perspective of an intermediate spring-frame or washer which I employ in the manner hereinafter described. Fig. 4 is a central horizontal section of the heel attachment, and Fig. 5 is a transverse section of the same.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I cause to be molded or otherwise produced a rubber heel section 1, which, as indicated in the drawings, is of a concavo-convex form. v The upper side of the rubber heel section or body is formed with a raised marginal portion, which is indicated at 2, this raised portion being continuous about the margin or outline of the heel-section. In molding the rubber heel I inclose or embed in the body thereof a metallic spring-frame or washer 3, which, although smaller, has somewhat the outline of the heel -section 1 and which is normally Serial No. 726,360. (No model.)

curved or bent to correspond to the curvature of said heel-section.

As indicated at 4, I form at desirable points in the heel-section 1 openings,which, as shown at 5, are continued through the internal spring-frame 3, these openings beingdesigned to receive the screws, nails, or other attaching devices through the medium of which the heel-section 1 is secured to the outer lift of the usual leather heel 6.

It is obvious that when the concavo-convex heel-section is screwed tightly against the leather heel-surface said heel-section will thus be forced to assume the straight or horizontal form of the leather heel lifts, and owing to the natural tendency of said heelsection to assume its normal curved 'form it will be seen that the tendency of the raised marginal portion 2 will be to cling closely to the surface of the leather, thereby overcomingthe usual tendency of rubber heelattachments toward lifting up or separating from the leather at the edges. It will be observed that the curved spring-frame 3, which is embedded, as desrri bed, in the rubber heel-section, will assist in imparting the desired curvature to the rubber and increase the tendency toward the latters retaining its concav'ed form.

Although I have described the rubber heel attachment as being so secured to theleather heel-surface as to bring the raised marginal portion 2 in contact with the leather,itis obvious that said heel attachment might be inverted, if so desired.

From the construction shown and described it will be observed that a desirable form of rubber heel attachment is provided for boot and shoe heels which will at alltimes cling closely to the boot or shoe heel surface and that the usual tendency of rubber heel at tachments to rise or separate from the leather heel at the edges Will be entirely obviated.
